Chemist prepares a solution of calcium sulfate (CaSO4) by measuring out 0.181 micro mol of calcium sulfate into a 100. mL volumetric flask and filling the flask to the mark with water.

Calculate the concentration in micro mol/L of the chemist's calcium sulfate solution. Be sure your answer has the correct number of significant digits.

Answer:

1.81 micromol/L.

Step-by-step explanation:

The concentration of a solution is calculated by dividing the amount of solute by the volume of the solution. In this case, the amount of calcium sulfate is 0.181 micromol and the volume of the solution is 100 mL. So, the concentration of calcium sulfate in the solution is (0.181 micro mol) / (100 mL) = **1.81 micro mol/L
